LIQUID-SPRAYING TRUCK.

Specification of Letters Pate t.

Patented Sept. 29, 1908.

. Application filed June 2, 1905. SerialNo. 263,386.

To all whom it may concern: I Be it known that I, GEORGE T. CONNOR, a citizen ofthe United States, and a resident of Stoneham, inthe county of Middlesex and State of Massachusetts, have invented an Improvement in Liquid-Spraying Trucks, of which the following description, in connection with the accompanying, drawing, is a specification, like letters on the drawings representing like parts. a V

This invention has for its object the production of a liquid spraying truck which, as it is moved over any surface, s rays theliquid thereon. This liquid may e used to lay any dust on the sprayed surface, orthe li uid may constitute a coating for a surface w ich maybe then finished or polished in any-usual or suitable manner, as by rubbing, etc.

Figure 1 is a section in the line at, Fig. 2, of a liquid spraying truck embodying the invention to be herein described in one of the best forms now known to me; Fig. 2 is a plan view of Fig. l, and Fig. 3 is a view of part of the tankand air receiverto show the arrangement of the nozzles. r

In the drawing, A re resents a frame having suitable handles A y which to move the same over the surface S. This frame has an axle A carrying wheels A preferably having rubber or other tires, so as not to mar the surface over which the truck is moved, which may be a floor. The truck-frame has bearings that receive the journals of a fluid-holdin tank D, and it also sustains one.or more cy inders B, four such cylindersbeing herein shown, each cylinder having therein a piston B. The cylinders have associated therewith a valve chamber B provided with a plurality of air inlets a, and a plurality of air outlets 0. said inlets and outlets being provided with any suitable or usual valve mechanism commonly employed in air compressors, so that as the plstons B operate, air will'be drawn in through the air inlets and forced outwardly throughthe air outlets. These parts are not shownin detailbecause they are such as are commonly found in air pumps.

ing floors.

time as to constitute a steady filling of the compressed air receiver to be described. In-

stead, however, of these throw arts being made as cranks, they may be ma e as eccentrics.

The Outlets a from the valve chamber are connected to flergible pipes. b that engage inlet pipes I) connected with a receiver 0 for compressed air and sustained by the fluid tank through straps 0 the ends of which are soldered or otherwise connected to said tank.

-The'receiver for the compressed air has a series ofvnozzles c that are in line with and occupy such relation to suitable nozzles 01 at the ends of pipes cl that enter the fluid tank D as to cause the compressed air in the receiverto be discharged with sufficient force therefrom across the open nozzles d to form a vacuum in said pipes, suck the fluid up therein, and spray the same onto the surface over which the truck is being moved. The fluid tank has an ordinary filling bushing closed by a cap (1 that will be removed when the tank is to be filled.

From the foregoing description it will be apparent that as the tank is run over the surface S the air compressors will be actuated to pump the air into the receiver 0 and maintain the same steadily under pressure, and

that the air leaving the receiver through the nozzles 0 will spray the same outwardly from the nozzles onto the surface S.

The rear end of the truck is provided with rollers c. 0

I have provided the apparatus described with a hood h having a depending lip 72,

' or coating of felt or other absorbent material m, n, which operates to absorb the liquid which may be sprayed thereagainst, and prevents such liquid from runnin ofi from these j parts and dripping onto the oor. Each piston B has connected to it a rod B The device is especially useful in re-finish- The finishing material of whatever nature may be placed in the tank and as the device is moved over the floor, such material will be sprayed onto the floor and applied thereto in a manner much better that could bedonewith an ordinary brush.

Having described my invention, What I claim as new and desire to secure by Letters Patent, is

In an apparatus of the class described, a truck, an air pump thereon, means to operate the pump by the movement of the truck, an air tank connected to the air pump, a fluidcontaining tank, and a hood embracing said tanks and provided With an opening, said hood having a trough at its lower edge, a lining of absorbent material for the hood, and. a

nozzle for each tank, said nozzles being arranged to form. an atomizer for delivering spray through the opening of the hood.

In testimony whereof, I have signed my 1 name to this specification, in the presence of two subscribing Witnesses.

GEORGE 'l. CONNOR.
